INSTALLING REFRIGERATOR IN
ENCLOSURE
NOTE: DO NOT install the appliance directly on
carpeting. Carpeting must be removed or
protected by a metal or wood panel beneath
the appliance, which extends at least full
width and depth of the appliance.
The refrigerator must be installed in a substantial enclo-
sure and must be level. When installing the refrigerator
in the enclosure, all areas within the recess in which the
refrigerator is installed must be sealed.
Make sure that there is a complete seal between the
front frame of the refrigerator and the top, sides and
bottom of the enclosure. A length of sealing strip is ap-
plied to the rear surface of the front frame for this pur-
pose. Also apply a sealing strip to the foremost floor of
the enclosure as shown in fig. 6. The sealing should
provide a complete isolation of the appliance’s combus-
tion system from the vehicle interior.
NOTE: Be careful not to damage the sealing strip when
the refrigerator is put in place.
Failure to follow the sequence in securing refrigerator in
enclosure can cause leakage between the frame and
cabinet.
When installing the refrigerator, the installer must block
the space between the storage cabinet and the top of
the refrigerator, otherwise heat will become trapped in
this space, making the top of the refrigerator hot, thus
reducing the efficiency of the unit.
Securing the Refrigerator
After the refrigerator is put in place, (insuring a combus-
tion seal at the front frame), the refrigerator is to be se-
cured in the enclosure with five screws (not included).
The screws have to be installed in the following order:
STEP 1: Four screws installed through the front
frame. See fig. 7.
STEP 2: One screw installed in rear base. See fig. 7.
In the parts bag there are plugs to be snapped in the
front frame to cover the four screw heads.
FIG. 6
GAS CONNECTION
Hook up to the gas supply line is accomplished at the
manual gas valve, which is furnished with a 3/8" SAE
(UNF 5/8" -18) male flare connection. All completed con-
nections should be checked for leaks with soapy water.
DO NOT use a flame to check for gas leaks.
The gas supply system must incorporate a pressure
regulator to maintain a supply pressure of not more than
11 inches water column.
When testing the gas supply system at test pressures in
excess of 1/2 psi, the refrigerator and its individual shutoff
valve must be disconnected from the gas supply piping
system.
When testing the gas supply system at pressures less
than or equal to 1/2 psi, the appliance must be isolated
from the gas supply piping system by closing its indi-
vidual manual shutoff valve.
In case detailed instructions on the installation and con-
nection to the gas supply are required, contact your
dealer or distributor.

TESTING LP GAS SAFETY SHUTOFF
The gas safety shutoff must be tested after the re-
frigerator is connected to the LP gas supply.
To test the gas safety shutoff, proceed as follows:
1. Start the refrigerator according to the instructions
for Gas Operation. See section Operating Instruc-
tions.
2. Check that the gas flame is lit. This can be ob-
served on the flame indicator E. The red indicator
is in the green field, (ON).
3. Close the gas valve by turning the knob A back to
“OFF” position.
4. Wait for one minute.
5. Remove burner cover plates. (See fig. 1).
Open the gas valve by turning knob A to position
(GAS) without pushing the buttons C and D. Apply
a non-corrosive commercial bubble solution to the
burner jet.
6. No bubbles should appear at the opening of the
burner jet. The presence of bubbles indicates a
defective gas safety shutoff, and service is re-
quired.
7. If no bubbles were present at the burner jet, the
gas safety valve is working properly. Rinse jet
thoroughly with fresh water before proceeding. Be
careful not to damage the burner jet.
Replace cover and turn the main switch OFF and
back ON. See instruction for Gas Operation,
section Operating Instructions. Normal operation of
the burner should return. Allow the burner to
operate for a minimum of 5 minutes.
ELECTRICAL CONNECTION
120 Volts AC Connection
The refrigerator is equipped with a three-prong
(grounded) plug for protection against shock hazards
and should be plugged directly into a properly grounded
three-prong receptacle. DO NOT cut or remove the
grounding prong from this plug. The free length of the
cord is 1.6 ft. and therefore recommended that the re-
ceptacle be located to the left side of the refrigerator
(viewed from the rear) and approximately 4-6 inches from
the floor (see FIG. 8). This allows easy accessibility
through the vent door. The cord should be routed to avoid
contacting the burner cover, flue cover, or any other com-
ponents that could damage the cord insulation.
12 Volts DC Connection
3-way refrigerator model
The 3-way refrigerator model RM 2353, has one termi-
nal block marked “12 volts DC” located at the bottom left
corner on the back of the refrigerator.
Correct polarity must be observed when connecting to
the DC supply.
DO NOT use the body or chassis of the vehicle as a
substitute for either of the two conductors. Do not con-
nect any other electrical equipment or lighting to the re-
frigerator circuit.
The refrigerator must be connected by a separate cir-
cuit to the battery with two wires of adequate capacity to
avoid voltage drop when the DC heater is being oper-
ated. The wire gauge should be chosen with consider-
ation to the length: refer to the Table below for wire size.
The 12-volt DC circuit must be fused. Maximum fuse
size is 20 amps.

Do NOT operate the refrigerator on 12 volt when the
vehicle is parked. The amperage draw of the 12-volt
DC heating element can discharge a battery in a very
short time. The installation of a 12-volt DC operated
refrigerator requires a relay to be installed on the
tow vehicle or in the caravan. The relay will auto-
matically shut off the 12 volt DC power to the refrig-
erator when the ignition is turned off. (See fig. 9).

OPERATING INSTRUCTIONS
1. To start the refrigerator, turn knob A to position
(GAS).
2. Turn the thermostat knob B to position 4.
3. Push the button C in until it reaches the bottom -
and hold, push the button D for the piezo igniter
several times to light the burner. This can be
observed on the flame indicator E. When the flame
is on, the red indicator is in the green field. (ON).
4. After the gas is lit keep the button C pressed for 10
seconds. Release the button and check that the
RED indicator is in the GREEN field, (ON).
5. To shut off the refrigerator turn the knob A to “OFF”
position.
NOTE: After changing an LP tank, or after a long shut
off period, the gas line is likely to be filled with air. You
may have to repeat the lighting procedure several times
to purge the air out of the gas lines.
IMPORTANCE OF LEVELING A
REFRIGERATOR
In an absorption refrigerator system, ammonia is lique-
fied in the finned condenser coil at the top rear of the
refrigerator. The liquid ammonia then flows into the
evaporator (inside the freezer section) and is exposed
to a circulating flow of hydrogen gas, which causes the
ammonia to evaporate, creating a cold condition in the
freezer.
The tubing in the evaporator section is specifically sloped
to provide a continuous movement of liquid ammonia,
flowing downward by gravity through this section. If the
refrigerator is operated when it is not level and the ve-
hicle is not moving, liquid ammonia will accumulate in
sections of the evaporator tubing. This will slow the cir-
culation of hydrogen and ammonia gas, or in severe
cases, completely block it, resulting in a loss of cooling.
Any time the vehicle is parked for several hours with the
refrigerator operating, the vehicle should be leveled to
prevent this loss of cooling.
The vehicle needs to be leveled only so it is comfortable
to live in (no noticeable sloping of floor or walls).
When the vehicle is moving, the leveling is not critical,
as the rolling and pitching movement of the vehicle will
pass to either side of level, keeping the liquid ammonia
from accumulating in the evaporator tubing.
GAS OPERATION
Before starting the refrigerator, check that all the manual
gas valves are in the ON position. Do not forget the
manual shutoff valve on the rear of the refrigerator see
FIG. 1.
! WARNING
Most LP gas appliances used in recreational ve-
hicles are vented to the outside of the vehicle.
When parked close to a gasoline pump, it is pos-
sible that the gasoline fumes could enter this
type of appliance and ignite from the burner
flame, CAUSING A FIRE OR AN EXPLOSION.
FOR YOUR SAFETY, when refueling, shut off all
LP gas appliances which are vented to the out-
side.

ELECTRIC OPERATION
1. Check to be sure that the power cord is properly
connected to the power supply. (See FIG. 8). If the
refrigerator is equipped for 12 volt DC operation,
the tow vehicle or caravan engine should be
running to prevent discharging the battery.
2. Turn the knob A to the position marked “AC” for
120 volt AC operation or “DC” for 12-volt DC
operation.
3. Turn the thermostat knob B to position 4.
4. To shut off the refrigerator turn the knob A to “OFF”
position.
THERMOSTAT
The refrigerator is equipped with a thermostat that can
be adjusted by turning the knob B to different setting to
maintain the desired cabinet temperature.
At OFF In gas operation, the thermostat closes its main
valve and the burner runs continuously at the
bypass rate, just enough to keep the burner lit.
In electrical operation, the contacts in the ther-
mostat are open and the heating elements are
off.
At MAX In gas operation, the thermostat allows the
burner to remain on high flame continuously. In
electric operation, the heating element is “ON”
continuously. Lowest cabinet and freezer tem-
peratures are obtained at this setting.
The thermostat can be adjusted between “MAX” and
“OFF” to obtain the desired cabinet temperature.
The closer the knob is to “MAX” - the colder the cabinet
temperature. The closer the knob is to “OFF” - the warmer
the cabinet temperature.
When the thermostat reaches the set temperature, it will
cut the burner back to bypass or, in electric operation,
shut off the heating element.
The setting of the thermostat is not critical, but we rec-
ommend it be adjusted to maintain a dry frost on the
cooling fins. Adjust the thermostat knob closer to “MAX”
when the outside temperature becomes warm.
HOW TO USE THE REFRIGERATOR
FOOD STORAGE COMPARTMENT
The food storage compartment is completely closed and
unventilated, which is necessary to maintain the required
low temperature for food storage. Consequently, foods
having a strong odor or those that absorb odors easily
should be covered. Vegetables, salads etc. should be
covered to retain their crispness. The coldest positions
in the refrigerator are under the cooling fins and at the
bottom of the refrigerator. The warmer areas are on the
upper door shelves. This should be considered when
placing different types of food in the refrigerator.
FROZEN FOOD STORAGE
COMPARTMENT
Quick frozen soft fruits and ice cream should be placed
in the coldest part of the compartment, which is at the
bottom of the aluminum liner. Frozen vegetables, may
be stored in any part of the compartment.
This compartment is not designed for deep or quick-
freezing of food. Meat or fish, whether raw or prepared,
can be stored in the frozen food storage compartment
provided they are precooled first in the refrigerator. They
can be stored about three times longer in the frozen food
compartment as compared to the fresh food compart-
ment. To prevent food from drying out, keep it in cov-
ered dishes, containers, plastic bags or wrapped in alu-
minum foil.
Ice cubes can be made in the freezer compartment.
For faster ice making, the tray should be placed in direct
contact with the bottom of the freezer compartment.
Ice making is accelerated if the thermostat knob B is
turned to the “MAX” setting.
It is a good idea to do this a few hours before the antici-
pated need for ice, but be sure to turn the thermostat
back to normal setting, usually about mid-setting when
the ice is formed. Food in the lower compartment may
be frozen if the setting is left on “MAX” position.
Total Refrigerated Volume 3 cu.ft.
DEFROSTING
Shut off the refrigerator by turning the knob A to “OFF”
position. Empty the refrigerator, leaving the drip tray un-
der the finned evaporator. Leave the cabinet and freezer
doors open. Filling the ice tray with hot water and plac-
ing it on the freezer shelf can reduce defrosting time.
NOTE: Defrost water runs from the drip tray to a recep-
tacle at the rear of the refrigerator where it normally
evaporates.
With a lot of defrost water as a result of heavy frosts
build up on the cooling fins, remove the drip tray and
turn it around. Replace the drip tray with the outlet on
the right side of the drip tray and put a bowl under the
outlet.
When the ice has melted, dry the interior of the refrig-
erator with a clean cloth. Replace the drip tray to its origi-
nal position and connect the draining tube.
Replace all food and set the thermostat to “MAX” for a
few hours. Then reset the thermostat to the desired set-
ting, usually at mid-setting.
DO NOT use a hot air blower. Permanent damage
could result from warping the metal or plastic parts.
DO NOT use a knife or an ice pick, or other sharp
tools to remove frost from the freezer compartment.
They can create a leak in the ammonia system.
CLEANING THE REFRIGERATOR
Cleaning the refrigerator is usually done after it is de-
frosted or put into storage. To clean the interior liner of
the refrigerator, use lukewarm weak soda solution. Use
only warm water to clean the finned evaporator, gasket,
ice tray and shelves.
NEVER use strong chemicals or abrasives to clean
these parts, as the protective surfaces will be dam-
aged. It is important to always keep the refrigerator
clean.
! CAUTION
11
SHUT- OFF (STORAGE PROCEDURE)
To shut off the refrigerator, turn the knob A to “OFF”
position. If the refrigerator will not be in operation for a
period of weeks, it should be emptied, defrosted, cleaned
and the door left ajar. The ice tray should also be dried
and kept outside the cabinet.
6. Remove some insulation wool so that the heater
is accessible.
7. Turn and lift the heater out of its pocket.
8. Fit the new heater into the pocket.
9. Reconnect the heater leads at the top.
10. Reset the insulation and close the lid of the boiler.
11. Replace cover at the burner housing.
12. Reinstall the refrigerator in the enclosure
see Item 2. Refrigerator Removal.
13. Check all connections for gas leaks.
14. Connect 120-volt power cord to the outlet and
reconnect or turn on the 12-volt DC power (if
available).
2. REFRIGERATOR REMOVAL
Before working on the refrigerator, make sure the AC
voltage and DC voltage leads (if available) are discon-
nected. Shut off the gas supply at the LP tank. Discon-
nect the gas supply line at the rear of the refrigerator.
Always use a back up wrench when loosening and tight-
ening connections.
Cap the gas supply line, loosen the screws anchoring
the refrigerator to the enclosure and slide the refrigera-
tor out of the compartment.
When replacing the refrigerator make sure that the seal-
ing strips are properly positioned.
Replacement is the reverse of removal. Check all con-
nections for gas leaks.
Refer to section INSTALLATION, page 4 to 8.
3. PERIODIC MAINTENANCE
To keep your Dometic refrigerator operating efficiently
and safely, periodic inspection and cleaning of several
components once or twice a year is recommended.
A. It is important to keep the area at the back of the
refrigerator clean. Check the lower vent, upper vent
and area between these openings for any obstruc-
tions such as bird/insect nests, spider webs, etc.
Clean the coils on the back of the refrigerator. Use
a soft bristled brush to dust off the coils.
